How a thermal roof survey works in Hampstead Garden Suburb
Thermal imaging is useful when a damp patch has no clear cause. Water can travel some distance under a roof covering before it shows inside, and the camera can show patterns that help us follow it. We combine the images with a visual inspection and moisture readings, so no conclusion rests on one method alone. If you’re worried about cold spots on ceilings under the roof and thin or uneven insulation in the roof, we can find out what’s behind it.
Many London roofs are hidden from the pavement: valley gutters behind parapets, dormers and flat-roofed rear additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. Weather on the day decides whether it goes ahead, in Hampstead Garden Suburb as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
What you get is a clear record of the roof on the day we saw it. It’s useful straight away, and a good reference for later.

How it works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit typically takes roughly 1–2 hours at most homes, with bigger or more complicated roofs taking longer. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us as you book.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it’s safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Preparing for the visit
- Leave a clear route to the loft
- Mention any parking restrictions on your street
- Have keys ready for side gates, garages or roof access doors

Advice
Rented homes, blocks and businesses
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
Letting agents frequently book on a landlord’s behalf. Access is agreed with the tenant ahead of time.
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Do not switch the heating off before the visit
- Use the report as a baseline for later checks
- Clear leaves from outlets and gutters each autumn
- Take photos of stains as they appear, so we can compare
Premium Surveys include an in-person consultation, so you can go through the images with us. There’s a 12-month follow-up too.
Consider a repeat survey after major work on the roof in suitable weather.
What we are asked to look at in Hampstead Garden Suburb
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, especially when it’s warm inside and cold outside.
These are some of the problems a survey can pick up:
- Leaks far from where the stain appears
- Areas of a flat roof that may hold water
- Moisture around outlets and upstands
- Heat escaping through the roof
For businesses in and around places such as Brent Cross Shopping Centre, large commercial roofs are often easiest to see by drone or thermal camera.
Questions to ask before booking
- What insurance they carry
- Whether VAT is added on top
- Is there a chance to talk the report through?
- Their report turnaround times
What a survey costs
All our prices include VAT. What changes the price is:
- Basic, Standard or Premium
- The use of thermal imaging or a drone
- Roof area
- Features like valleys, chimneys, dormers and parapets
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Prices start from £400, including VAT.

Hampstead Garden Suburb questions
How do I find out if my home in Hampstead Garden Suburb is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Will parking be an issue for a roof survey in Hampstead Garden Suburb?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. Points are put by urgency where it matters.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and cannot tell you, and back them up with a visual inspection and moisture readings.
Can a thermal camera see water?
Not directly. It shows temperature, and wet materials frequently behave differently from dry ones. We confirm what it suggests with moisture readings.
How long is the visit?
Time on site depends on the roof, but most surveys take roughly 1–2 hours at a typical home; commercial roofs usually need 3–4 hours. The written report follows by email.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it’s warm inside and cold outside. We look from the loft as well, where there is safe access.

Parapets, valleys and junctions

Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. We check those patches with moisture readings.
Thermal roof surveys around Hampstead Garden Suburb
About 0.8 miles south-east lies Heath Hall, a reminder of how long the area around Hampstead Garden Suburb has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
Hotels and guest houses near Hampstead Garden Suburb cannot easily close rooms for a leak, so it is worth knowing the roof’s condition. For site and facilities teams at buildings like The Henrietta Barnett School, a drone or thermal camera can show a large roof in a single visit.
